Well, perhaps they could use SOME of the original trilogy characters to bring in mainstream interest and provide support for the newer, unfamiliar characters.

Of all the First Class characters, I'm interested in Magneto, Emma Frost, Havok, Banshee and Xavier.

I don't know how on earth they are going to make Jennifer Lawrence's Mystique grow into Rebecca's version; it's going to need several films to make that transition from insecurity to being a cold, hard, kick-ass reptile. And I don't think they will ever give us the luxury of several films focusing on the First Class cast.

While I would like to see the First Class series give us young versions of Scott, Jean and Storm and the introduction of Polaris, I don't know if they will bother with that.
